Deleted blog but people are still liking my posts????

I deleted it quite a while ago yet I just got an email saying someone liked one of my posts. I don't understand why it is so hard to get rid of a blog. If you give the option to delete, then that should delete it. I have seen several other people have had the same problem which is a bit ridiculous. Not to mention, apparently my email and password is still with this site even though I wanted to completely delete my account.
